I went ahead and ordered all four books mentioned here. 100 Masterpieces was $60 used on Amazon and the other three totaled $75 new, so I figured I couldn't lose.
I haven't received Sinclaire, yet, but the others are very nice.
100 Masterpieces is viable as a coffee table book in our academic household, but it is not as "accessible" as the others, maybe. I'm very impressed with the Compton collection. Do you guys know if his pieces are displayed anywhere? I'm not very far from Elkhart at all...
I didn't catch that Lethal Elegance was fittings only (my primary interest is blades), but it is very nice. It has, actually, depressed me a bit. I had thought that I could probably look hard and find a couple of $200-ish tsuba and not too expensive fuchi/kashira that would be representative for me and make me happy--but now I'm realizing that I will never be happy with pieces I can afford...
Art of the Samurai is superb. It has gorgeous photos and would interest anyone, I think.
Thanks for the good advice, guys. I think my wife will accept that these objects or art are worth spending some money on if I go to the Chicago sword show...but I think she will not be as impressed by anything I'm actually likely to bring home as a beginner!
